I'm totally new into this DSLR-thing and I'm planning to buy a Canon 550D or 600D. At the moment it'd be body only, not the kit, because I'll be in need of a
good lens for close-up-shots
(hardware, technical devices) at a good value for the money. Canon, Tamron ... - doesn't matter.

Secondary the cam would be for inhouse-shots of persons in low-light-conditions.
